Renesas RMWV6416AGSA-5S2#KA0

Overview

RMWV6416AGSA-5S2#KA0 from Renesas Electronics is a 64Mb Advanced LPSRAM organized as 4,194,304-word × 16-bit (or 8,388,608-word × 8-bit), operating from a single 2.7–3.6V supply with 55ns max access time and 1.2µA typical standby current at +25°C. It supports battery backup operation and is used in portable instrumentation, industrial HMI, and low-power embedded controllers requiring non-volatile data retention during power loss.

For engineers reviewing the RMWV6416AGSA-5S2#KA0 datasheet, RMWV6416AGSA-5S2#KA0 pinout, RMWV6416AGSA-5S2#KA0 application, or RMWV6416AGSA-5S2#KA0 equivalent, key selection criteria include TSOP (I) package compatibility, byte/word mode flexibility via BYTE# control, low-voltage data retention down to 1.5V, and TTL-compatible I/O signaling without level translation.

Technical Context

This SRAM implements dual chip select architecture (CS1# active-low, CS2 active-high) enabling hierarchical memory mapping in multi-bank systems. Its address space supports both word (A0–A21) and byte (A–1 to A21) addressing modes, with dedicated LB#/UB# pins for independent 8-bit lane control and BYTE# pin enabling mode selection between 16-bit word and 8-bit byte configurations.

Operation includes three distinct data retention entry methods-via CS2 ≤ 0.2V, CS1# ≥ VCC−0.2V (with CS2 high), or simultaneous LB#/UB# ≥ VCC−0.2V-each guaranteeing data hold at VCC as low as 1.5V while drawing ≤36µA at +85°C. Output drivers are three-state, directly TTL-compatible, and support high-impedance transitions within 20ns of control signal deactivation.

FAQ

What is the maximum access time specification for RMWV6416AGSA-5S2#KA0?

The RMWV6416AGSA-5S2#KA0 has a maximum access time of 55 ns under all operating conditions (VCC = 2.7–3.6 V, TA = −40°C to +85°C). This value is guaranteed across voltage and temperature ranges and applies to both address-to-data and chip-select-to-output timing paths, ensuring deterministic performance in real-time embedded systems.

Does RMWV6416AGSA-5S2#KA0 support true byte-write operations?

Yes, RMWV6416AGSA-5S2#KA0 supports true byte-write operations using LB# and UB# pins. When BYTE# is asserted low, A–1 becomes valid and DQ0–DQ7 or DQ8–DQ15 can be written independently. The device's operation table confirms separate write cycles for lower byte, upper byte, and full word-enabling precise memory updates without read-modify-write overhead.

What is the minimum supply voltage required to retain data in RMWV6416AGSA-5S2#KA0?

The RMWV6416AGSA-5S2#KA0 retains stored data down to a minimum supply voltage of 1.5 V, provided one of the three retention entry conditions is met: CS2 ≤ 0.2 V, CS1# ≥ VCC−0.2 V (with CS2 high), or LB# = UB# ≥ VCC−0.2 V (with CS1# low). At 1.5 V, data retention current remains ≤36 µA at +85°C per the latest Rev. 2.00 datasheet.

Is RMWV6416AGSA-5S2#KA0 pin-compatible with other members of the RMWV6416A family?

RMWV6416AGSA-5S2#KA0 shares identical pinout and signal definitions with RMWV6416AGSD-5S2 (52-pin µTSOP II) and RMWV6416AGBG-5S2 (48-ball FBGA) only for common signals (A0–A21, DQ0–DQ15, CS1#, CS2, WE#, OE#, LB#, UB#, VCC, VSS). However, BYTE# is absent on FBGA and functionally mapped differently on µTSOP II; thus, direct PCB substitution requires layout verification per package-specific pin arrangement diagrams.

How does the BYTE# pin affect addressing mode in RMWV6416AGSA-5S2#KA0?

In RMWV6416AGSA-5S2#KA0, the BYTE# pin configures the device's addressing mode: when BYTE# ≥ VCC−0.2 V, it operates in 16-bit word mode (A0–A21 active); when BYTE# ≤ 0.2 V, it enters 8-bit byte mode (A–1 and A0–A20 active). This hardware-selectable mode eliminates software configuration overhead and ensures deterministic bus-width matching to host processors.
